The medicinal plants constitute a source of raw material for approximately 25% of the prescribed drugs which
play an important role in the field of health care. Unscientific exploitation of natural vegetation has led to a large
scale denudation and reducti
on in
-

population of medicinal plants. The loss of genetic diversity in the gene pool
of

these medicinal plants
is

the most serious environmental problem
-
mankind
facing
today. Hence, the main aim
of the present study is conservation of certain medicinal
plants by

ex
-
situ
conservation method and
-

improvement
of

the soil fertility by the application of eco friendly biofertilizers
(
Glomus mosseae

and
Glomus fasiculatum

)
.

Medicinal plants selected for the present investigations are
Andrographis paniculata,

Costus pictus
,
Gymnema

and
Adhatoda
for their various pharmacological properties and also for their active principles. Pot trial
experiments were conducted to study the responses of these medicinal plants to AM fungi association (bio
fertilizers). Result
s envisaged that the total yield in terms of fresh and dry biomass production has been increased.
Different yield attributes
viz.,

height, number of branches
have been found to be varying with treatments with the
result being highest in the case of applica
tion of bio

fertilizers
has been found to be varied with treatments, being
highest in the application of bio

bi
o
diversity in sole (SFB) and mixed
field bean (MFB) cropping systems in and around Bengaluru (12

58’ N, 770 35’ E). In SFB only field bean was
cultivated. In MFB, traditional cultivars of finger millet (
Eleusine coracana
), fodder sorghum (
Sorghum bicolor
),
castor (
Ricinus communis
), niger (
Guizotica coracana
) and field bean (
Lablab niger
Medick) were

cultivated.
MFB supported on an average 37 bird species with 148 individuals/km
2
while SFB supported 17 species with 30
individuals /km
2
. MFB supported 13 plant species with 85250 individuals/km

in

SFB.
MFB supported 16 butterfly species with 799 individuals/km
2
compared to SFB with 10
species and 557 individuals /km
2
. MFB supported 30 beetle species with 76500 individuals/km

2
compared to sole
crop which supported 30 species with 60250 individuals/ km
2
.

T
he greater species richness at MFB was due to the greater physical habitat variability. Crop yield loss and bird
species richness were negatively correlated (r =
-
0.8740), (P< 0.5).At study sites crop yield loss and index of
species richness were inversely

related. Yield loss and insect species richness were also negatively and
significantly correlated (r =
-
0.9130), (P<0.05). Supplementing either sole or mixed crop with bird perches
(stubs), shrubs and tress along fields borders and restricted use of pesti
cides facilitated agro
-
biodiversity and
mitigated problems of pests and diseases. MFB (C:B ratio 1:4.1)
faci
litated sustainable crop yields

proving
economically, environmentally and ecologically sound than SFB (1:2.3) to the growers.

,
-
one of the productive ecosystem
s

of Uttara Kannada,
-

located in the
west coast of India
,

is known for its verdant mangrove diversity. Totally 13 species of true mangrove
-

belonging
to 8 genera and 6 family

were recorded inhabiting this area.
. In addition to this, there is associated mangrove
flora
-

comprising 7 species (5
-
genera and 3
-
family). Among mangroves, family Rhizophoraceae represents 5
species and 3
-
genera where

as in associated flora dominant family was Fabaceae. This mangrove ecosystem
harbours diversified fin and shell fish but present study focused mainly on brachyuran crab diversity. In all, 20
species of crabs belonging to 14 genera and 6 families have bee
n recorded from sub littoral zone of the estuary.
Dominant genera represented are Ocypode and Sesarma. But, Scylla serrata is the only commercial species found
amidst the rich floral growth of Rhizophora apiculata and Avicennia sp. associated with soft mu
d. Some crab
species are site specific with respect to mangrove flora. Portunus sanguinolentus and P. pelagicus were absent in
this biotope. Sesarma edwarsi and Varuna litterata were observed
especially
during the rainy season when low
salinity regime
is
established (between 2 to 5 psu). Crab fishery, their landing and culture aspects along the
estuary is also discussed briefly to give some information on their culture potentials. Conversion of mangrove
area into shrimp farm, industrialization, sand mi
ning and excavation of shell fossils are major threat
s

to crab
diversity in this area.

Keywords:

Brachyuran, Mangrove, Estuary, Crab fishery and Diversity.

Urban trees serve many useful functions such as climate change
mitigation by carbon sequestration
, air

quality
improvement by air pollution abatement, biodiversity conservation, source of ecosystem goods and service to
urban inhabitants. They also have aesthetic, socio
-
religious and recreational value in urban conte
xt. In spite of the
importanc
e, they have not received much
scientific attention. This paper investigates the diversity and density of
tree species growing both within the built environment as well as road
-
side avenues in the seaside town of Karwar
which

i
s the

administrative headquarters of Uttara Ka
nnada district of Karnataka.
The total area of the town is

27.15 m2 and
population is 62,973.

The tree flora of Karwar comprises of about 100 species in which about 70%
are wild indigenous species. The other 30
% involves exotic and cultivated species. The top five dominant species
are
Mangifera indica

(wild

mango, 20.016% of total tree population),
Polyalthia longifolia

(False Ashoka,
12.544%),
Peltophorum pterocarpum

( Yellow flame tree, 6.763%),
Samania sama
n

( Rain tree, 5.072%) and
Artocarpus heterophyllus

( Jackfruit, 5.045%). The tree diversity represents a good assemblage of different utility
categories such as wild and cultivated fruit yielding trees, shade and ornamental trees, sacred and religious tre
es,
etc. Besi
des the high proportion of old
trees of wild mango and jackfruit, presence of other wild fruit yielding
trees like
Artocarpus incisus

and
Spondias pinnata
, large sized sacred trees such as
Ficus religiosa

and
F.
benghalensis
, rare medicinal species such as
Garcinia indica
,
Saraca asoca
,
Terminalia bellirica
, etc., are some
of the notable features of the urban tree flora of Karwar.

Only two species of
Calotropis

R. Br.
genus namely
Calotropis

procera

R. Br.
and
C. gigantea

R. Br.
are
usually reported in literature. Study of variation in these species distributed over a stretch of about hundred and
fifty kilometers in the eastern Uttar Pradesh suggests the presence of at least four types of plants. These plants
can be easily identif
ied as
C. gigantea

blue (cgb) and
C. gigantea
white (cgw),
Calotropis

procera

blue (cpb)
and
C. procera
white (cpw),. Simple morphological characters like maximum attainable plant height, corolla
shape and corolla color are sufficient for constructing arti
ficial dichotomous keys and their unambiguous
identification. A preliminary systematic study of these four types of plants on the basis of scatter plots between
leaf length and leaf width also indicates their clear differentiation. Study of such variations

in
Calotropis

leading to identification of clear differentiation and development of reproductive isolation barriers may help us
identify suitable species or ecotypes/genotypes that can be tried further for tapping their full potential as
medicinal and pet
ro

Establishment of BIAL resulted in massive landscape changes, denudation of vegetation, large scale movement of
rural masses of people away from BIAL area, increased tr
affic frequency on road, chemical pollution and water
pollution. There was a 25% reduction in mammal species. Out of the fourteen state forests three have been
deforested for development of BIAL. These changes have affected biodiversity in 4500 acres of BI

Wetlands are the most diverse ecosystems, where the main focus is given to water birds. However, in this
ecosystem, the invertebrates especially the insects form functionally important group. In present study an attempt
has been made to document the butter
fly fauna around three different irrigation reservoirs in the semi arid zone of
Central Gujarat. All the three reservoirs are surrounded by different agricultural matrices and face different kinds
of anthropogenic pressure. The Species Richness, Shannon We
iner Diversity index (H') and Evenness (E) and the
Percentage abundance of the different butterfly families are assessed with seasonal differences. 46 species of
butterflies belonging to 5 families of Order Lepidoptera were observed around the three reserv
oirs with 40 species
noted around the Nationally Important Wetland, Wadhwana Irrigation Reservoir, whereas 31 around Jawla
Irrigation Reservoir with rural surrounding and 26 around Timbi Irrigation reservoirs with rural
-
urban gradient.
Around larger wetlan
ds, majority of species were found. At the wetland under rural
-
urban gradient the species
found showed the influence of modern urban vegetation. The influence of size of reservoir, agricultural matrix
and human movements is discussed with the seasonal diff
erences in the species composition and variation in their
abundance.

are known to acquire toxic alkaloids from their host plants making the caterpillars and adults toxic to their
predators. The host plants of these butterflies belong to Family
-
Asclepiadaceae

including a medic
inally important
plant
Holostemma ada
-
kodien,
which has been listed out as vulnerable and rare in the FRLHT red list of
medicinal plants. In the current study, we investigated the energetics of striped tiger larvae with two different
milkweed plants as


against

Holostemma.
The study aimed to check the biological association between larvae
with their different host plants. The experimental setup was done with three sets each consisting of 30 newly
emerged larvae of striped tiger. The first and second sets

of larvae were made to feed on
Cynanchum dalhousiee
and
Asclepias curassavica

respectively. At the same time the third set of larvae were made to feed on
Holostemma ada
-
kodien.

The larvae of first and second set used 1.6068±0.15 g of
Cynanchum dalhousiee

leaves
and 1.6464±0.13 g of
Asclepias curassavica
leaves for their metamorphosis into pupae respectively. However it
was observed that the third set of larvae which fed on
Holostemma
used 1.868±0.16 g of leave
s

for their
metamorphosis. The result obtained
in the current study clearly demonstrates that the Striped Tiger larvae damage
the leaves of
Holostemma
more than that of other two host plants as they require more leaves for the their
metamorphosis. Considering the vulnerability status of medicinally imp
ortant plant
Holostemma,
the larvae of
striped tiger
act
as reasonable pest
s

in wild condition.

BUTTERFLY DIVERSITY AT BANNERGHATTA NATIONAL PARK


Deepanjali Tamang

Christ University

In the present study, observation made in the Butterfly Park, Bannerghatta

shows the presence of a great
number of varieties of species of butterflies. Some rare species like Southern birdwing
-
was

also observed. Many
other species like the Baronet, Common castor, Crimson rose, common Emigrant, common Mormon,
Mot
tled Emigrants etc., were also observed. The park displayed a rich floral surrounding for the proliferation
of the butterflies along with many other insects. Though many species were identified and many unknown
species were observed, the popul
ations of different species were not very high. This may be due to change in
the climatic condition or impact of human activities.

TERRESTRIAL AND AQUATIC BIODIVERSITY AT THE VALLEY SCHOOL


EXPERIENCES AND CHALLENGES


The Valley School

The valley school is located on the edges of the Bannerghatta

reserve forest. Over the last 30 years, the school has
made many efforts to conserve the biodiversity as well as the water bodies on the campus. Due to our efforts, the
campus has a large number of indigenous species of trees. We have also been able to co
nserve the fresh water
lake on campus.

As
a
part of the environment education curriculum, the class 9 students will be undertaking a project next term
(Nov
-
Dec) to study and document the biodiversity on the campus. The area of study for the project would
include
(i) terrestrial biodiversity along the perimeter of the lake and the stream that carries the run
-
off from the lake (ii)
aquatic biodiversity in the lake and (iii) testing the water quality in the lake. The students will also identify the
challenges

to biodiversity conservation in The school.

The students will present the summary of the project during the Lake 2010 symposium. The objective is to share
The Valley School’s efforts in conservation and land

care.
